Question

What is the slope-intercept form equation of the line that passes through (2, 4) and (4, 10)?

O y = -3x - 2
O y = -3x + 2
O y = 3x + 2
O y = 3x - 2

Answer 1

y = 3x - 2.

Explanation:

The slope of the line (m) = (10-4)/(4-2)

= 3.

y - y1 = m(x - x1)

y - 10 = 3(x - 4)

y = 3x - 12 + 10

y = 3x - 2.

Answer 2

⊹˚ʚ ❑Answer︰The slope is 3!

⊹˚ʚ ❑Explanation︰use the formula y2-y1 over x2-x1
